“…Since its introduction, the ZCQ has become one of the primary outcome measures to report on treatment results in patients with LSS. 5 The ZCQ has been translated and validated into several languages [6][7][8][9][10][11][12][13][14] and has shown to be a reliable and valid diseasespecific questionnaire for patients with LSS. There have been 9 language translations, with over 120 articles published using the ZCQ.…”

Study Design: Validation study. Objectives: To translate and validate the Zurich Claudication Questionnaire (ZCQ) into a Danish version of the disease-specific patient-reported outcome measure (PROM) for patients with lumbar spinal stenosis (LSS), which assesses symptom severity, physical function, and satisfaction after surgery. Method: Translation into a Danish version of the original questionnaire by back- and forward-translating the questionnaire and finally transforming a prefinal test version into a final and cross-cultural adapted version. Validation was performed as a cohort study assessing floor-ceiling effects, internal consistency, test-retest reproducibility, criterion validity, discriminant validity, and responsiveness to change. Results: Fifty-three patients were consecutively included in the study, 53 healthy controls were matched. Floor effect was seen in the postoperative data. Internal consistency, Cronbach’s alpha was good to excellent. Substantial test-retest reproducibility was found using Cohen’s weighted kappa. The Danish ZCQ showed moderate to strong association with similar domains of Oswestry Disability Index, Short Form 36, Euro QoL 5D, visual analogue scale–leg and back. The questionnaire showed significant responsiveness to change and a significant discriminant validity between LSS patients and healthy controls. Conclusion: This study shows the Danish translation of the original ZCQ to be well understood by Danish patients. The Danish version is furthermore a reliable and valid questionnaire, which is responsive to change.

Study Design. Retrospective cross-sectional analysis.Objective. The aim of this study was to establish the strength of relationship between the Patient-reported Outcomes Measurement Information System (PROMIS) Adult Depression (AD), Physical Function (PF), and Pain Interference (PI) with the Swiss Spinal Stenosis Questionnaire (SSSQ) in assessing lumbar spinal stenosis (LSS). Summary of Background Data. In 2009, there were >35,000 surgeries for LSS, which amounted to $1.65 billion in health care cost. By 2021, there will be >2.4 million people in the United States with symptomatic LSS. There is an increasing emphasis on patient-reported outcomes (PROs) to define value in medicine. Therefore, it would be beneficial to compare PROMIS, a universal PRO, against the SSSQ, the ''criterion standard'' for assessing LSS. Methods. Eighty-two patients with LSS completing the PROMIS and SSSQ were enrolled. Per existing institutional protocol, PROMIS AD, PF, and PI were completed at every clinic visit. Linear regression analysis was then performed to evaluate how well the SSSQ and PROMIS scores correlated to each other. Results. When linear regression was performed for pretreatment values, the R 2 value for the SSSQ PF versus PROMIS PF was 0.14 (P ¼ 0.0008), whereas the R 2 value for the SSSQ symptom severity versus PROMIS PI was 0.03 (P ¼ 0.13). The R 2 value for the combined SSSQ physical function and symptom severity versus PROMIS AD was 0.07 (P ¼ 0.02). When post-treatment SSSQ satisfaction scores were correlated to postoperative PROMIS AD, PI, and PF scores, the R 2 values for a good linear fit were 0.13, 0.25, and 0.18 respectively (P values: 0.01, 0.003, and 0.003). Conclusion. Pre-treatment PROMIS scores do not adequately capture the disease-specific impact of spinal stenosis, but postoperative PROMIS scores better reflect outcomes after surgery for LSS. PROMIS scores should not be used in isolation to assess outcomes in patients with LSS.
